A novel liposomal Clodronate depletes tumor-associated macrophages in primary and metastatic melanoma: Anti-angiogenic and anti-tumor effects

The depletion of tumor-associated macrophages (TAMs), involved in different stages of cancer development and progression, is an appealing strategy in cancer therapy. We developed novel Clodronate-containing liposomes (Clo-Lipo-DOTAP) presenting physicochemical properties (size distribution, polydispersity index and Z-potential) suited for safe storage and injections. In vitro, Clo-Lipo-DOTAP inhibited proliferation, reduced viability and induced...
